The 24-year-old civil engineer explained that if it was not for the enthusiasm and encouragement of Glasgow Club Running Network she would never have put on her running shoes.
She went from no experience of distance running to competing in the 10K in just four months and is the perfect example of how we can all make our lives active and healthier if we put our minds to it.
Mary, from King's Park, Glasgow, joined the Running Network last February with the goal of taking part in the city event in May.
So positive was the experience she went on to take part in the Glasgow half marathon in October, completing it in a respectable 2hrs 10mins.
"I was a complete beginner and had never run any great distance before, so I signed up to the beginners' group, where we ran twice a week with two network coaches," she said.
"This was a great way to build up fitness levels, with the coaches varying the routes, increasing the distances each week and mixing it up with speed sessions, which I really enjoyed."
She said the network's pasta parties were a great way to keep motivation levels high and keep the training light-hearted and fun in the build-up to each race, by running through the city centre to Di Maggio's and meeting other runners from the network.
She said finishing the 10K in an hour gave her a great sense of achievement and something to be very proud of.
She said: "I continued running with the network twice a week during the summer and did the half marathon alongside one of the network coaches who helped to keep me going - another milestone in my fledgling running career.
"The next step for me will be the Edinburgh Marathon in May and I will train with the Running Network's marathon training course, which starts in a few weeks.
"I have gone from a complete beginner to marathon runner in a short space of time and it is all thanks to the Running Network."
For anyone inspired by Mary and thinking of running but not sure where to start, there is plenty of help to get in training for the Bupa Great Women's 10K on May 11.
